新型肥料硅谷复合肥在玉米生产中的应用

Application of New Fertilizer Silicon Valley Compound Fertilizer in Maize Production

为探究新型肥料硅谷复合肥在玉米生产中的应用效果,以传统施肥方式(底肥+追肥)为对照,选择新型肥料硅谷复合肥、包衣尿素及玉米专用缓释肥3种肥料田间试验,通过比较各处理的干物质积累量、籽粒灌浆速率、产量及经济效益等指标评价各种肥料的效果。结果表明,肥料种类显著影响玉米干物质的积累,硅谷复合肥能促进玉米植株地上部干物质的积累、增加籽粒灌浆速率,玉米成熟期地上部干物质积累量较对照增加10.93%,最大籽粒灌浆速率较习惯施肥对照增加2.27%,平均籽粒灌浆速率较对照增加1.28%,其通过增加行粒数及百粒重来提高玉米产量,行粒数较习惯施肥对照增加4.90%,百粒重较习惯施肥对照增加1.19%,较习惯施肥对照增产11.09%,净收益增加305.52元·(667 m^(2))^(-1)。施用硅谷复合肥能提高产量、增加收益,可在玉米生产中推广应用。

In order to investigate the effect of the new fertilizer Silicon Valley compound fertilizer in maize production,the study selected three fertilizers consist of Silicon Valley compound fertilizer,coated urea and maize dedicated slow-release fertilizer,using the traditional fertilizer application mode(substrate+chasing)as the control,and evaluated the effect of each fertilizer by comparing the dry matter accumulation,seed filling rate,yield and economic benefits of each treatment.The results showed that the type of fertilizer significantly affected the accumulation of dry matter in maize,and Silicon Valley compound fertilizer could promote the accumulation of aboveground dry matter in maize plants and increase the rate of grain filling,and the accumulation of aboveground dry matter in maize at maturity increased by 10.93%,the maximum rate of grain filling increased by 2.27%,and the average rate of grain filling increased by 1.28%compared with conventioal fertilization control,and it increased the yield of maize by increasing grains of rows and the weight of 100 grains.The yield of maize was improved by increasing grains of rows and the weight of 100 grains,which increased by 4.90%and 1.19%compared conventioal fertilization the control,resulting in a yield increase of 11.09%and a net income of 305.52 yuan·(667 m^(2))^(-1).The application of Silicon Valley compound fertilizer can improve yield and increase earnings,and can be applied in a large area instead of common fertilizer maize production.
